Join Mick Jerram of Gecko canoeing on a beautiful Land for Wildlife property for a bird watching walk with one of Katherine’s most experienced wildlife tour guides. Find out more about birds in the Katherine region the Land for Wildlife program. This is part of Aussie Backyard Bird Count (https://aussiebirdcount.org.au/) And YES Gouldian finches have been recorded on the property- you never know!

Directions- Drive towards Nitmiluk Gorge from the stuart highway. 20.3 kms on the right there is a small turn off which will be marked. Map and further directions to be added. PLease park opposite Maude Creek Lodge.

Land for Wildlife hosted a Fire Workshop back in May with a focus on Fire and the effects on wildlife, particularly arboreal mammals.

The subject is of course complex and controversial but vital to the management of our landscapes and the ecology of our native species.

To try a give a balanced perspective we organised a very well known fire ecologist Alan Andersen to present alongside Natalie Rossiter on the findings of fire experiments that have been conducted over several years in bushland at the Territory Wildlife Park and then for participants to be given an insight into the effect of fire on Wildlife and landscapes from a land manager’s point of view with Andrew Spiers giving a walk and talk, who also has many years of land management experience from National Parks and teaching and observing in the field. There are of course many other experts in fire and many studies and perspectives to consider.

Over 20 people attended the workshop, including fire volunteer and land managers. They were shown the fire plots at The Territory Wildlife Park and then invited for a walk and talk on Andrew Spier’s property on the nearby Blackmore River flood plain. Greg Miles also attended and offered his perspective from being a long term ranger and Land Manager in Kakadu as well as managing his own Land for Wildlife property.

Often it is perceived that there is too much fire in our landscapes in the Top End, often started by people with little knowledge of fire ecology (such as people out on quad bikes having fun or just driving along). Many preventative “prescribed” burns are carried out to induce an early (dry season) cool burn rather than a later hotter “accidental” burn when winds are higher and fuel load is drier.

Gamba grass is a huge factor in affecting the fire regime. (see below). Fire management or regime involves the factors of frequency, patch size and shape burnt and fuel load (related to time of year) and conditions (dew point, wind etc. also related to time of year)

IN Summary-

Savannah Landscapes have been shaped by fire over a very long time in Australia to be dominant in species with fire survival mechanisms that thrive with fire such as Eucalypts and grasses.

Riverine areas, Monsoon forests and wet lands are more sensitive areas of vegetation and frequent fire does not allow them to regenerate as a Savannah landscape does. Often as these landscapes are bordered by woodland there can be a knock on or edge effect.

Gamba grass is a considerable factor in adding to fuel load and curing only to burn later, when fire is hot and to intense for other native species to recover.

The fire experiments have found that burns on the same area of bushland every 4 years (early or even later on) creates greater biodiversity (Andrew Andersen)

The longer term ecological interactions of species is the important factor that fire effects rather than the immediate effect on wildlife (Andrew Andersen)

Fire effects different species differently, there are some winners and some losers (AA)

Generally when fire is absent the tree layer becomes more mature and dense and fire sensitive species start to colonise, the grass layer reduces.

In the case of arboreal mammals, the absence of fire is favourable as mid-story fruiting plants, rainforest fruiting plants are more abundant as a food source and old growth trees stand for longer and harbour hollows.

It is very difficult to manage fire on a large property as there are many “Wild fires” which are uninvited. Many flowering plants are lost when this happens on the floodplains.

It really is down to the land manager to decide how they shape the landscape they manage with (or without) fire

Greg Miles introduced the idea of wet season burning, which we may invite LFW members to learn more about later in the year, below is a short summary:

Most land managers have adopted the advice of fire experts and been doing early dry season burning (EDS) for the protection of assets and to prevent destructive late season fires (LDS) later in the year. While there are very good reasons to use EDS for this purpose, I would argue that what suites asset protection may not suit the natural ecology. After 40 years of involvement in natural area fire management I have come to the view that EDS burning is cumulatively killing the woodlands of the Top End. There is a mountain of circumstantial evidence to support this hypothesis, but it is contradicted in part by some research findings, especially CSIRO’s Kapalga Fire Experiment of the 1980’s. But it is clear to me that frequent EDS burning promotes annual grasses, especially native speargrass. Burning encourages more grassy fuel which encourages hotter burning which encourages more grass – ad infinitum. Thus a “grass fire cycle” is created. This cycle is improving the hunting success of cats and is slowly killing the pre-European ecology of the woodlands. Add in Cane Toads and invasive African Grasses and you have the perfect storm. But there is a way to break the grass fuel cycle. In my view the solution is to reduce the amount of EDS burning and instead, dramatically increase the amount of early wet season burning (EWS). Sure there are many practical problems with doing this, but they can be managed. WSB is more intellectually demanding than EDS burning, but that should not be seen as a reason not to do it. My prediction is that if land managers were to switch from EDS to EWS burning they would see a rapid turn around in the ecological health of the natural woodlands landscape.

Greening Australia (Darwin) is holding some community workshops in April and May about recognising and growing native plants; these workshops are open to anyone interested.

Each workshop is $40 or all 3 for $100 plus a free “Native Plants for Top End Gardens” book if you sign up to all of them.

All workshops run from 9am to 4pm (lunch included)

Please see the flyer below.

Workshop One

Where- Greening Australia nursery and nearby bush location

When– Saturday 1st April

Content- Plant identification and seed collection

Learn how to identify plants through their features with a focus on natives and how to observe them in their natural vegetation communities (in a short excursion to local bushland) and how to make a herbarium specimen.

Learn the different types of seeds, the protocols for seed collection, how and when to collect seeds form different species and how to prepare and store them.

Workshop Two

Where- Greening Australia nursery

When- Saturday 22nd April

Content- An introduction to native plant propagation

Learn how to store and treat seed, how to sow, and the best time of the year to do this, to add success to growing your own native plants. Improve your techniques with growing from cuttings, how to propagate different plants. potting up plants and what medium to use.

Workshop Three

Where- A Darwin garden (TBC)

When- Saturday May 27th

Content – Designing and planting a small garden with native wildlife attracting and bush tucker plants

Learn about the best Top End native plant to choose for small gardens that are wildlife attracting or bush tucker plants. Learn how to design a small space with plant size, shape, texture, and water requirements in mind. Learn how to prepare and plant out a garden space.

Bird week is such a great way to show case our feathered friends that are so abundant in the Top End; we put together a couple of small events for members and friends of Land for Wildlife, back in October. A hot and in one case wet time of year, we still had a great group of people along at both events.

The best things always come with collaboration and a guided walk of Fogg Dam was hosted for Land for Wildlife members and friends of in association with Parks and Wildlife at Fogg Dam. After low rainfalls last wet season the dam was at low levels, but started filling up as we were talking our guided walk- with some of the first rains of the year. We were joined by ‘Friends of Fogg Dam’ members Mary and Janis who talked about their work, the birds and take stunning photos of the birdlife.

After a drive across the dam wall, a talk on looking after bird habitat and a good soaking we went into the very wonderful woodland walk to see what else we could spot. We ended up with a great list of wetland and woodland birds. I would love to thank Jo Scott, who helped organise the event and sadly has since left the role of Community engagement Officer at PWC.

We held a small “Landholder’s walk and talk” with Denise Lawungkurr Goodfellow who has written ‘Birds of Australia’s Top End’ and ‘Birds of Palmerston’ with her partner Michael. They have a 20 acre (8 hectare) property with some wonderful flooded Sandsheet and wet season creek areas in Darwin River. Denise tells some great stories and emphasises that watching birds is about sitting with country and watching behaviour, not just ticking them from a checklist; it is about getting to know them and their habitat.

Thanks Denise and Michael for your great contribution to wildlife education.
